Wheezing during exercise

I've started getting a little wheezy recently and I don't know what's causing it. I've booked a doctors appointment so I can get it checked out but in the mean time I wanted to know if anyone else has had this?

I never used to get it but it's gradually been getting worse. Today I did HIIT and lower body and during the HIIT I was wheezing really badly. I don't want it to get in the way of my workouts because I've been staying on track recently but it's making it really hard.

Does anyone else deal with this?
